Metal

Metal

Metals are a group of elements that are typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity. They are generally found in the periodic table's s-block and d-block. Metals are distinguished by their ability to form positive ions (cations) in solution.

Properties

Physical properties

Metals are generally malleable and ductile, meaning they can be hammered into thin sheets or drawn into wires. They are lustrous, reflecting light to appear shiny. Metals are also good conductors of electricity and heat.

Chemical properties

Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. This property makes them good reducing agents. Metals also react with oxygen in the air to form metal oxides.

Occurrence and extraction

Metals are found in the earth's crust and in the sea. Some metals are found in their native state, while others are obtained through mining and refining processes.

Uses

Metals have a wide range of uses due to their varied properties. They are used in construction, transportation, electronics, and many other industries.

Health effects

Exposure to certain metals can have adverse health effects, including metal poisoning. However, some metals are essential for life and play important roles in biological processes.
